Hello!
We can solve this algebraically
2x + 5 = 3 + 2(x+1)
Distribute the 2
2x + 5 = 3 + 2x + 2
combine like terms
2x + 5 = 2x + 5
Since both sides of the equation is the same all values of x make the equation true
The answer is A
Hope this helps!
Answer:
C. 1 ≤ x ≤ 9 or x is between 1 and 9, inclusive
Step-by-step explanation:
I took this quiz before
F(x) = (3+x)/(x-3)
f(a+2) = (3+a+2)/(a+2-3) ... replace every x with a+2
f(a+2) = (a+3+2)/(a+2-3)
f(a+2) = (a+5)/(a-1)
f(a+2) = (5+a)/(a-1)
The answer is choice A
